Problems solved by technology

This technology has certain defects, mainly reflected in the fact that each second RNC must forward the data received from the UE to the first RNC, which greatly increases the traffic between the first RNC and the second RNC, and the network very heavy load

Embodiment Construction

[0032]The idea of ​​the present invention is: because the UE sends measurement reports to each RNC in a predetermined period or according to user events, and for each RNC, according to the measurement report, it is possible to know which data link in each RNC has the best quality. Make each RNC unpack the measurement report, and then upload the data with the best link quality to the core network according to the measurement report. Compared with the prior art that only the first RNC unpacks the measurement report, and other second RNCs are required to forward data to the first RNC, this reduces the amount of uplink macrodiversity data transmission during soft handover and also reduces Network load.

[0033] Figure 3-5 It is an embodiment in which the uplink macrodiversity method of the mobile communication system is applied to the traditional mobile communication network architecture. Figure 5 It is a schematic flow chart of an embodiment of the uplink macrodiversity method of ...

Abstract

The present invention provides an upper macro diversity method of mobile communication system, under the soft switching course, including: unpacking measurement report when the radio network controller or base station receiving the measurement report aquiring link quality of each data link; analyzing the unpacked measurement report, if the quality for executing the first radio network controller of the upper macro diversity or the link being highest, then direct uploading the data received from the data link to the core network equipment. The invetion processes unpacking to the measurement report to judge which data lind has the best quality, direct uploading the best data lind to the core network equipment by the radio network controller or base station for the upper macro diversity, data or signaling not the best data does not transmitted between the radio network controller or base station under the course, reducing network communications volume of the upper macro diversity when processing the soft switching, and reducing the network load.

Description

Technical field [0001] The present invention relates to an uplink macrodiversity method of a mobile communication system, in particular to a method for user equipment in a mobile communication system to perform uplink macrodiversity merge on signals of multiple base stations when soft handover is performed across cells. Background technique [0002] In the mobile communication system, the mobile terminal usually needs to switch the signal connection between the original cell and the new cell when it crosses the cell. Take the Universal Mobile Telecommunications System (UMTS) as an example, when the user equipment (User Equipment, (Referred to as UE) during handover, in order to ensure the quality of the radio link, a continuous signal connection needs to be maintained. That is to say, the UE needs to establish a connection with the new cell before disconnecting from the old cell, so that it can be Keep the signal connection at the time. This switching method is called soft switch...
